我正在我的 android studio 应用程序中进行注册行为（java），并且我有一个性别广播组。当我单击单选按钮选择性别时，我遇到了应用程序崩溃的问题。我不确定我的代码是否适合将信息存储在解析中，或者我如何尝试在解析中存储是问题

我想你是setOnCheckedChangeListener()在初始化单选按钮之前打电话的。所以试着把你的初始化器移到顶部，然后是单选按钮。

    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_register);

           //initialize first
                    mUserFirstname = (EditText) findViewById(R.id.firstNameRegisterEditText);
                    mUserLastname = (EditText) findViewById(R.id.lastNameRegisterEditText);
                    mUsername = (EditText) findViewById(R.id.userNameRegisterEditText);
                    mUserPassword = (EditText) findViewById(R.id.passwordRegisterEditText);
                    mUserEmail = (EditText) findViewById(R.id.emailRegisterEditText);
                    mUserPhonenumber = (EditText) findViewById(R.id.phoneNumberRegisterEditText);
                    mUserPostalcode = (EditText) findViewById(R.id.postalCodeRegisterEditText);
                    mGender = (RadioGroup) findViewById(R.id.radioGroup);
                    mMale = (RadioButton) findViewById(R.id.maleGenderRegisterEditText);
                    mFemale = (RadioButton) findViewById(R.id.femaleGenderRegisterEditText);
                    mDob = (EditText) findViewById(R.id.dateofBirthEditText);
                    mRegisterbutton = (Button) findViewById(R.id.registerButton);

      //listen to checked changes next
           mMale.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
               @Override
               public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                   if (isChecked) {ParseUser user = new ParseUser();
                       user.put(COLUMN_GENDER, MALE);
                       user.saveInBackground(); // if you want to save immediately

                   }
               }
           });

            mFemale.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    if (isChecked) {ParseUser user = new ParseUser();
                        user.put(COLUMN_GENDER, FEMALE);
                        user.saveInBackground(); // if you want to save immediately
                    }
                }
            });







                    //Listen to Register button click
